ACI’s A/RH Duct Series Sensor is a Relative Humidity Transmitter designed for use with electronic controllers in commercial HVAC building management systems. The RH Duct Transmitter can be powered with either AC or DC supply voltage and is field selectable with a 4-20 mA, 0-5 VDC, or 0-10 VDC output signal that is equivalent to 0 to 100% RH.Calibration Although ACI sensors are designed and engineered to drift less than other competitive humidity sensors on the market, over time, factors like env …

The Belimo 10 Step process for sizing and selecting a damper actuator:1)What is the Area of the damper?We need to find the height and width of the damper. The customer may provide this in millimetres (mm). If so, multiply the millimeters by 0.039 to convert it into inches. Once in Inches, multiply the height and width and divide by 144 to get the area in square ft (sq. ft). If the customer provides it is Feet (ft), no need to convert it to inches. The height and width can just be multiplie …
